Thailand is developing new legislation on responsible business conduct that would impose statutory obligations on large enterprises to manage human rights and environmental risks throughout their operations and supply chains. The Draft Act on the Promotion of Responsible Business Conduct, commonly referred to as the Human Rights and Environmental Due Diligence (HRDD) Bill, has been developed through extensive consultation involving a wide range of stakeholders, with the Ministry of Justice playing a leading role. If enacted, the HRDD bill would reshape how certain large businesses operate and manage their supply chains, reflecting a recognition of international standards and global concerns regarding human rights and environmental protection. By introducing legally binding due diligence obligations, the draft aims to ensure that businesses operating in Thailand are held accountable for adverse impacts throughout their operations and supply chains, in line with emerging global legal frameworks. Who Will Have to Comply? The HRDD bill primarily targets large enterprises based on their annual revenue thresholds: Manufacturing businesses with annual revenue exceeding THB 500 million Wholesale, retail, or service businesses with annual revenue exceeding THB 300 million The draft would also cover state-owned enterprises and foreign businesses operating in Thailand if their operations meet the applicable revenue thresholds. What Does Human Rights and Environmental Due Diligence Involve? Under the HRDD bill, due diligence is not a one-time checklist but an ongoing process with several key requirements: Adopt and publicly disclose a sustainability policy. Businesses must commit publicly to respecting human rights and protecting the environment, and must integrate this policy into corporate governance and risk management systems. Identify and assess risks. Companies must identify and assess risks of human rights violations and environmental harm across their operations and value chains. Prevent or reduce risks. Businesses must implement effective and proportionate measures to prevent or mitigate

Thailand’s Department of Business Development (DBD), through its Office of Central Company and Partnership Registration, has released multiple draft orders for public consultation until December 12, 2025. These draft orders aim to strengthen the business registration process, with a focus on the requirements for establishing and amending the principal office address of a partnership or limited company, verification of authorized signatories, and measures to identify and prevent registrations involving persons linked to suspicious or high-risk activities. The draft orders’ proposed requirements are outlined below. Principal Office Verification The principal office address of a partnership or limited company, including house registration code, house number, full address details, and building name, must be fully aligned with the civil registry. The registrar will strictly verify this before accepting any registration or amendment. If the address used for registration is already registered for at least five other companies, the company must submit a consent letter from the person authorized to allow use of the principal office, along with supporting documents proving the right to use the address. Signatory Certification Compliance Duties Persons certifying directors’ signatures on registration forms are responsible for verifying their identities, maintaining up-to-date information, and complying with the requirements of the DBD’s Biz Regist digital registration system. Certain supporting documents proving the qualifications of certifying persons are also required, with some exceptions for specific professional roles. Identity and qualification verification must be renewed upon the completion of one year from the date of registration as a certifying person, or if the certification credentials expire before the one-year period ends, in accordance with the verification requirements. Verification of Suspicious Parties Any partner, shareholder, or director linked to a predicate offense will be required to meet with the registrar in person for further verification steps. For all parties related to a company

On October 22, 2025, the Thai government posted a directive not to grant gambling licenses for gambling involving poker nationwide to crack down on illegal gambling activities. The directive was issued by Thailand’s Ministry of Interior to align with government policies to prevent the legalization of all types of gambling businesses, including poker as a sporting activity. This will result in the revocation of poker activities as sport and institute a strict ban on such activities nationwide. Businesses should note the new government’s strict approach toward gambling activities as the legal situation regarding gambling in the country continues to draw close attention.
